Thunderbird, again: now, after working fine all the time for some weeks, today included, until this very moment, it now has decided not to take in any more emails and has put the following message (shown in the attached GIF). By the way: the button with the hardly visible writing actually says “OK”. This is one more of TB’s exclusives.
If someone knows of some rather simple way around of it, I’ll be grateful, particularly as long as I learn about it before I eviscerate TB and then I am reduced to finding some other client that actually works and, most specially, works well with macOS Big Sur.
